History of Negative and Imaginary Numbers

Mathematics is hated or disliked by people responsible for mastering mathematics. In such a world with such strong emotions to mathematics, negative and complex numbers are considered to be incorrect in most histories. Naturally, many young students are concerned about new unknown topics, especially for mathematicians over thousands of years, such as negative numbers and complex numbers. In Tennessee province, according to state standards, negative numbers were introduced in sixth graders as extension of rational number system, and complex numbers were introduced in high school algebra.

In order to understand what the time of imagination is, you must first understand what the imaginary number is. Imaginary is a number and if you squat it it will give you a negative number. As you can imagine, if you squared real numbers, the answer is yes. So how can you have a number, squares and give you something negative? Well, this is not a real number but "imaginary number". Just by defining objects abstractly, when your squares give you -1, you give it a name, usually the square root of -1 is called i. That's all

The imaginary number is a number, and squaring results in a negative number. Basically, the imaginary number is the square root of a negative number, and there is no concrete value. This is not a real number, but it can not be quantized with a digit string. Since imaginary numbers exist and are used in mathematics, it is "real number". Usually it is represented by a symbol, and the imaginary number is represented by the symbol j in the electron (because "current" is indicated). Imaginary numbers are particularly suitable for electricity, especially for alternating current (AC) electronics. AC is a sinusoidal wave that changes positive and negative. It may be very difficult to combine AC currents. Because they may not match the wave properly. Using virtual current and real numbers helps to calculate and avoid electric shock using AC.
